Wind Load Capacity

In getting your new windows in Columbus there are many things that will impact the quality and desirability of the window. This includes aesthetics and design, of course. It also includes efficiency ratings, which will impact comfort levels in the home and heating and cooling costs. But one factor that is less discussed today (which should not be the case) is the wind load capacity of a window. Unfamiliar with the term? Let our team fill you in on the details.

APCO is dedicated to offering clients the best in reliable services and products. As part of this we go through great effort to ensure our windows are all ENERGY STAR® rated and provided by leading, trusted manufacturers. We understand the importance of wind load capacity, heat gain, and more, and we want to ensure you do as well!

What Is Wind Load Capacity in a Window?

The wind load of a window, often also referred to as the Design pressure or DP is the load that a window can withstand in a measurement of wind. The pounds per square inch of pressure a window can deal with. Essentially this boils down to simply how much wind, or how high the pressure of wind, a  window can handle and remain fully functional.

A higher rating means the window can take on more wind load without incurring common forms of damage or performance drops. As an example, an “average” wind load resistance rating for a window is about 119 mph wind resistance, while a top-end window might boast resistances of 170 or above.

It’s important to keep in mind that finding your ideal DP rating is about finding what works for you. Many homes will never encounter wind pressures of even 110, and thus opting for the highest rating can be somewhat of an unnecessary investment. However, you do want a high enough rating to counter even the possibility of a problem. That’s why at APCO we typically suggest and offer windows with a wind-load rating of 143 mph.

Balancing Wind Load with Energy-Efficiency

The conundrum one faces here is that there are many factors that impact the strength of a window, including:

  • Internal window chambers and bends. Chambers and bends used in window design can have a considerable impact on strength and wind/snow resistances.
  • Walls. Multiple walls within a window add a layer of defense for each wall, which is why single-wall windows aren’t frequently seen in higher quality windows.
  • Reinforcement. The use of design reinforcement, of course, is an excellent way to add strength. And by choosing the right material, you can gain this without losing efficiency.

A common trouble in balancing these things is that metal reinforced windows tout some of the highest resistances. However they also can cost you a lot in efficiency, generating a lot of excess heat gain that can create discomfort and higher costs in a home. This is why higher quality manufacturers have moved to using fiberglass and vinyl reinforcement.
